Add Evelant ExtensionMulti-Model AI
Evelant routes your messages to three model providers from one interface, so you don't need separate subscriptions or tabs open for each.
Models are grouped into tiers rather than by vendor, because the tier is what decides both what your plan can run and what a message costs.
| Tier | Models | Credit cost |
|---|---|---|
| Base | Gemini 3.1 Flash-Lite, Claude Haiku 4.5, ChatGPT 5.4 Mini | 1 credit |
| Advanced | Gemini 3.7 Flash, Gemini 3.1 Pro (Preview) | 2 credits |
| Advanced | Claude Sonnet 5, Claude 4.6 Sonnet | 3 credits |
| Advanced | ChatGPT 5.5 | 6 credits |
| Legacy | Gemini 2.5 Flash, Gemini 2.5 Flash-Lite, Gemini 3 Flash (Preview) | 1 credit |
| Legacy | Gemini 2.5 Pro, ChatGPT 5.4 Auto | 2 credits |
| Legacy | ChatGPT 5.4 Reasoning, Claude 4.5 Sonnet, Claude 3.7 Sonnet | 3 credits |
| Your keys | DeepSeek, Kimi, GLM, Qwen, Ollama | No credits — billed to your key |
Legacy is a shelf, not a lower rung: those models still run exactly as they did, but Auto never routes to them. It picks between Base and Advanced.
See Model Credit Costs for exactly how credit weighting works.
Availability: Free and guest run the Base tier — which is all three vendors, not one, since Base holds a Gemini, a Claude and a ChatGPT model. Pro unlocks the Advanced and Legacy tiers, including the reasoning models. Max adds the “your keys” tier on top, where you supply the credential and the messages cost no credits — that tier stays out of the model picker until you connect a key in Settings, since we hold no credential for those models ourselves.
Switch models per session from the model selector in the chat panel footer — no need to start a new conversation.
